A study published in the journal Appetite reports that what you eat can affect the amount and quality of your sleep. "In general, we know that those who report between [seven to eight] hours of sleep each night are most likely to experience better overall health and well-being, so we simply asked the question, 'Are there differences in the diet of those who report shorter sleep, longer sleep, or standard sleep patterns?'" study researcher Michael A. Grandner, Ph.D., of the Center for Sleep and Circadian Neurobiology at the university, said in a statement.
